Flat Isomeria (continued)

Metameria or compensation isomeria

This isomerism occurs between isomers that belong to the same function but differ in the position of a heteroatom in the carbon chain.

The heteroatom must always be between carbons.


Function Isomeria

Occurs when isomers belong to different functions. The most common isomers for this type of isomerism are:

- alcohol and ether
- aldehyde and ketone
- carboxylic acid and ester


- alcohol and ether: C2H6O

- aldehyde and ketone: C3H6O

- carboxylic acid and ester: C4H8O2
